69FNH SCAR MK20 SSR 7.62

The SCAR heavy in sniper variant. Semi auto, dead nuts accurate, and commonality with the other SCAR platforms for field servicing. Light weight, powerful, and easy. Jack of all trades... If anyone has ever really had to tote a rifle around for any amount of time, they'd appreciate the lighter ones. As for being a sniper. It means more than anything to stay light. At less than 10lbs, its among the lightest.

As for the M-x Barrett, you can keep that 40lb pig. Not to mention the heavy rounds.

Great weapon! It does the job without hesitation or trouble. And come on it made some of the longest shots ever up to 2km!
